Prescription Drug Coverage

Atropen Medicare Coverage

Medicare plans do not typically cover Atropen. Learn more about Atropen and find Medicare Advantage plans in your area that cover other prescription drugs.
Chemical name: Atropine

Brand name: Atropen

Typical type: Injection1

Atropen is a medication used to treat poisoning by specific substances and insecticides. The Atropen injector pen is only available as a name brand.

Atropen is a medication that contains the active ingredient atropine. Atropen is used as an antidote for poisoning from insecticides and nerve agents that contain cholinesterase.

Atropen contains the active ingredient Atropine. Atropine itself (not in the Atropen injector form) may be used for a number of other more common medical treatments, including pupil dilation before eye exams or eye procedures.

Common side effects include blurry eyes, constipation, dizziness, headache, dry mouth, dilated pupils, pain where the shot was given, upset stomach and vomiting.

How much does Atropen cost with Medicare?

If Medicare Part B covers Atropen treatments for you because you meet the qualifying conditions, you’ll typically pay 0% to 20% of the Medicare-approved amount for the Atropen prescription price, after you meet your Part B deductible.

In 2024, the Medicare Part B deductible is $240 per year. Once you pay this amount, you’ll pay the remaining copay costs Medicare Part B doesn’t cover.

Does Medicare cover Atropen?

Medicare Part B covers drugs administered by a medical provider for qualified beneficiaries.

You don’t need a Medicare Advantage plan or a Medicare Part D prescription drug plan to get Atropen coverage.1

If you have either type of private drug plan, you’re enrolled in Medicare Part B, and you qualify for Medicare coverage of Atropen, your Part B benefits will cover Atropen.

Some Medicare Advantage plans and Medicare Part D plans cover other prescription drugs that aren’t administered in a doctor’s office or by a medical professional.

  • Part D plans or Medicare Advantage plan that cover drugs include copay amounts that can range widely from one plan to another. Plan members may also be responsible for meeting a deductible before the plan’s drug coverage kicks in.

  • Medicare Advantage plans that offer prescription drug coverage are called Medicare Advantage Prescription Drug Plans (MA-PD). 89% of 2023 Medicare Advantage plans included prescription drug coverage.2

  • Medicare prescription drugs plans each have their own formulary, or drug list, that details what prescription drugs are covered by the plan and how they are covered.

Drug coverage may vary based on plan availability. You may be able to find Medicare Advantage plan options in your area that cover prescription drugs. We represent carriers such as Humana, UnitedHealthcare®, Anthem Blue Cross and Blue Shield, Aetna, Cigna Healthcare, Wellcare, or Kaiser Permanente.
